The Ninyo & Morore test results also confirm that construction is accepatable without mitigating measures and do not pose a signficiant threat to human health. The three sets of test results performed after initial testing do not support initial results which indicated elevated soil vapor levels.
The Ninyo & Moore report is available to the public on the City website in summary form (link provided below) and will also be made available in its entirety to prospective bidders on the Sawmill property.
The report does not recommend additional remediation of the site nor property use restrictions. Ninyo & Moore offer some foundation design mitigation recommendations for developers to consider in order to minimize the potential for any soil vapor intrusion into buildings. These recommendations are not requirements to obtain a building permit, nor would they generally add significantly to the cost of construction.
The City is currently preparing to re-open bidding on the southern portion of the Sawmill property.
